If you receive the message "Failed to initiate update. Please contact technical support, then perhaps you are the owner of a controller whose firmware cannot be updated remotely.

In this case, you can still update the controller, for this we are ready to send you an updated replacement controller free of charge, and then take the old controller away from you. If you refrain from updating, this will not create any additional difficulties for you. Your old controller will continue to be fully supported by all our subsequent software versions, and you can also use the option to replace it later if you suddenly need it at some point.
